In my view using functions on tuples feels wrong (but there are always exceptions). They seem like intrinsic “values/units” that are constructed with the tuple notation and smashed with destructuring (via pattern-matching).
Strangely with maps I’m quite the opposite - they seem more complex and free form than tuples so I tend towards using functions rather than (yet another) map notation (I guess Clojure made me operator averse/function friendly). I keep having to remind myself:
- that I can pattern match on maps
- and that with map pattern matching ignoring parts is implicit
List are in the middle. I have to be backed into a corner before I use hd/1 or tl/1 preferring the cons notation - probably because that is the bread and butter for pattern matching (for destructuring) - otherwise they are dominated by higher order functions (… and Enum.at/3 makes me cringe).
